Question

我有一个索引，其映射定义如下：

  "mappings": {
      "profile": {
        "properties": {
          "_key": {
            "type": "string"
          },
          "username": {
            "type": "string"
          },
          "groups": {
            "type": "nested",
            "include_in_parent": True,
            "properties": {
              "name": {
                "type": "string"
              },
            }
          }
       }
    }

但是，当我尝试在API（localhost:9200/myindex）中查看索引详细信息时，groups的映射不会打印出"type"和"include_in_parent"字段所有。这是正常的吗？ e.g。

GET http://127.0.0.1:9201/myindex/profile/_mapping?pretty
Response:
{
    "myindex" : {
        "mappings" : {
            "profile" : {
                "properties" : {
                    "_key" : {
                        "type" : "string"
                    },
                    "username" : {
                        "type" : "string"
                    },
                    "groups" : {   // where is "nested"?
                        "properties" : {
                            "name" : {
                                "type" : "string"
                            }
                        }
                    }
                }
            }
        }
    }
}

我在groups上执行嵌套查询时遇到了麻烦。在尝试以下查询时，我收到nested object under path [groups] is not of nested type之类的错误：

POST http://127.0.0.1:9200/myindex/profile/_search
{
  "query": {
    "filtered": {
        "query": {
            "match_all": {}
        },
        "filter": {
            "nested": {
                "path": "groups",
                "filter": {
                    "term": {
                        "groups.name": "foo"
                    }
                }
            }
        }
    }
  }
}

如何确保我已正确定义我的映射？

Answer 1

我创建了像

这样的索引

TypeError: b'foo' is not JSON serializable

我把我的映射像这样

PUT myindex

然后，当您执行

时，您将获得预期的结果

PUT myindex/_mapping/profile
{
  "profile": {
    "properties": {
      "_key": {
        "type": "string"
      },
      "username": {
        "type": "string"
      },
      "groups": {
        "type": "nested",
        "include_in_parent": true,
        "properties": {
          "name": {
            "type": "string"
          }
        }
      }
    }
  }
}

注意：我使用了Marvel-Sense

在检索索引信息时，嵌套映射不会打印为“嵌套”？
